Application filed November 2. 1911. Serial No. 658,156.

Fig. 2. Fig. 4 is a sectional view on the 50 line H of Fig. 2.

Similar reference characters indicate corresponding parts throughout the several v ews of the drawlngs.

whereby the separator may be operated, and when it is desired to stop the separator, the said belt is shifted onto the loose pulley 26, as usual.

separator box, in which is rotatably archine or refining engine preferably of the Jordan type, (not shown), although the same may be of any other Well-known con struction. 5 Extending into the open'top oi the separater box is a perforated Wat-er sprinkling tube or pipe 28 provided with a medial union. 29 connecting it to a Water supply pipe 30, and through this pipe 28 is delivered Water to the pulp material delivered into the separator for the Washing of the forainino'us body 7 thereof., so as to Wash away any obstruct-ions which may close the orifices therein.

In the operation of the separator, the pulp material is delivered from the trough 5 through the pipe or tube 12 to the interior of the toraininous body 7 of the separator, it being understood of course that the same is driven so as to revolve in the separator box 6. The pulp contained within the body of the separator is acted upon, so as to become strained by the foraniinous body 7, thereby causing the fine pulp in rial. tosbe screened through the foraminous body and discharged into the separator box 43, "While any foreign matterpresent in the pulp delivered into the foraminous body is separz'eted from the fine pulp and is caused to gravitate to the larger end of the separator, whence it is discharged through the discharge ring 9 into any suitablereceptacle. In this manner the pulp passed. through the screenis delivered in a fine condition free of foreign matter into the separator box 6, whence itis delivered through the delivery pipe 27 to. the pulp Working machine or refining engine. Thus, in this manner the Work on the refining engine will not he interfered. with, as there Will not be present in the pulp delivered thereto any foreign matter which would damage or break the refining engine when tIQfLUIlQ the iul delivered thereto.

It is of course understood that changes variations and l'liiodifieations in the invention may be resorted to without departing from the spirit or sacrificing any of the edantages ot the same, and come properly Within the scope of the appended claims.

What is claimed is:

1. A machine or the class described co1nprising a separator box having a oonveyer outlet leading from its bottom a pulp feed ing trough located rul'jacent one end of said box, a toraniinous trusto -conioal shaped sieve rotatsibly 'journaled in said bozt, a deliyery pipe leading "from said trough into one end of said sieve a. di rhurge ring mounted interiorly off said sieve at the other end thereof and eending a distance thereinto, and means connected with said ring for rotating said sieve. I

2. A machine of the class described coinprising a seps "ator box having a conveyer outlet leading from its buttons, a pulp feeding trough located adjacent one end o't box, a sieve rotatable in. said box a delivery pipe connected to said trough and projecting into said sieve, a head closing one end of said sieve and having a, sleeve engaging said delirerypipe, an annular track carried by the other end of said sieve at cross beam carried by said box, bearings carried by said beams and adapted to receive said track and a plurality of spaced reinforcing bars connecting said head with said ring.
